# Delete a kanban column

`DELETE /api/boards/{boardId}/columns/{itemId}`

## Request

- Base URL: `https://cnvs.app`
- URL: `https://cnvs.app/api/boards/{boardId}/columns/{itemId}`
- Auth: none declared

Mirrors the MCP `delete_column` tool. Deletes the column AND every task inside it. Discover column ids via `GET /json/{id}` (the `columns[]` array).

## Response `200`

Deleted.

- object
  - `ok` boolean
  - `id` string

## Other responses

- `400`: Invalid input (missing or malformed board id).
- `401`: Board is access-locked and the request did not carry a valid key. `lockMode` tells the client whether to prompt for a code or just disable write UI.
- `404`: Board does not exist or was deleted within the 30-day tombstone window.
- `429`: Rate limit exceeded. Standard REST/MCP: 60 requests/10s/board; valid X-Import-Token infrastructure tier: 600/10s/board; browser WebSocket always 60/10s/board. REST/MCP enforcement is soft per-isolate; WebSocket enforcement is strong per Durable Object.
